Step 2

Use the manufacturer guidelines to determine the wire length to be stripped.

Step 3

Insert the ground wire into the ring terminal lug, and using a crimping tool, crimp the terminal to the wire. See the following figure. If two ring terminals are being used, repeat this action for a second ring terminal.

Figure 8. Crimping the Ring Terminal

Step 4

Slide the ground screw through the terminal.

Step 5

Insert the ground screw into the ground screw opening.

Step 6

Use a ratcheting torque screwdriver to tighten the ground screws and ring terminal to the switch front panel to 3.5 in-lb (0.4 Nm). The torque must not exceed 3.5 in-lb (0.4 Nm).

Step 7

Attach the other end of the ground wire to a grounded, bare metal surface, such as a ground bus, a grounded DIN rail, or a grounded bare rack.

Connecting the earth ground wire

Procedure

Step 1

Measure a single length of stranded copper wire long enough to connect the power supply to the earth ground. The wire color might differ depending on the country of use.

The power supply must be grounded in accordance with local/state/national codes and per the installation guidelines of the power supply.

Step 2

Connect one end of the stranded copper wire to a grounded bare metal surface, such as a ground bus, a grounded DIN rail, or a grounded bare rack.

Connect the other end of the wire to the grounding screw on the power supply. Only wire with insulation should extend from the connection.

Note

 
The position of the power supply may vary on different switch models.

Step 3

Tighten the earth-ground wire connection screw.

Connecting Destination Ports

This section provides information about connecting to the destination ports.

Connecting to 10/100 and 10/100/1G/2.5G Ports

The 10/100 and 10/100/1G/2.5G ports automatically configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce performance or result in no link.

To maximize performance, choose one of these methods for configuring the Ethernet ports:

  • Let the ports autonegotiate both speed and duplex.

  • Set the port speed and duplex parameters on both ends of the connection.


Caution

To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures.

Procedure

Step 1

When connecting to workstations, servers, routers, and Cisco IP phones, connect a straight-through cable to a M12 connector (IP67 Torque: 4.5 to 7.0 in-lbs or 0.5 to 0.8 Nm) on the front panel.

When connecting to 1G/2.5G compatible devices, use a twisted four-pair, Category 5 or higher cable.

The auto-MDIX feature is enabled by default.

Step 2

Connect the other end of the cable to a M12 connector on the other device. The port LED turns on when both the switch and the connected device have established a link.

The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for loops. This can take up to 30 seconds and then the port LED turns green. If the port LED does not turn on:

  • The device at the other end might not be turned on.

  • There might be a cable problem or a problem with the adapter installed in the attached device. See Chapter 4, “Troubleshooting,” for solutions to cabling problems.

Step 3

Reconfigure and reboot the connected device if necessary.

Step 4

Repeat Steps 1 through 3 to connect each device.
